Abstract: An electrode for a fuel cell with an operating temperature of about 100° C. or more. The electrode has an electrode catalyst layer that includes an electrode catalyst with a conductive carrier and catalyst particles supported on the conductive carrier. The electrode catalyst includes an acid impregnated electrode catalyst in which the conductive carrier is impregnated with an acid component having proton conductivity by a heat treatment with the acid component in advance, and a non-impregnated electrode catalyst. The acid impregnated electrode catalyst and the non-impregnated electrode catalyst are uniformly distributed in the electrode catalyst layer.

Abstract: A sealing member for a fuel cell includes a pair of belts that include non-gas transmitting layers formed of aromatic polyimide or aluminum and thermoplastic resin layers. The belts are disposed such that the thermoplastic resin layers of the belts face each other, and the thermoplastic resin layers in outer edge portions of the belts are thermally bonded to each other. In a fuel cell, an inner portion of the belts engage the electrolyte membrane.
